Specification of Letters Patent.

Patented July 2,1912.

Application filed July .6, 1910. Serial No. 570,546.

To all whom itmay concern: I

Be it known that I, Amos C. BARTLETT, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Reversible-Window-Bodrd Sets; and I do hereby declare the following to be a full clear, and exact description of the invention, such 'as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to ventilating apparatus, and more particularly to an apparatus which is adapted to be arranged in a window casing.

The object of the invention is to provide an ap stratus of this character having a novel improved construction and an l'anglenient of parts which enables it to be rea ''ly and conveniently adjusted to either blow fresh air into a room, the foul air from the room.

To' these ends the invention consists in thefeatures of construction and combinations of parts hereinafter described and referred to in the claims.-

The various features of the invention will or to exhaust be readily understood from an inspection of the accompanying drawings and the fol lowing detailed description of the apparatus shown therein.

In the drawings, Figure 1 is a plan view partly in section of a ventilating apparatus of the invention in their preferred forms and Fig. 2 is a sectional elevation on line 2-2, Fig. 1, look ing in the direction of the arrows.

As shown in the drawings, the various parts of the apparatus are secured upon a partition 1 in the form of a window board which may be readily secured to the window casing at the top or bottom, as may be most convenient. As shown, the-devices for securing the window board in place consist of clips 2 secured at the opposite ends of flanges 3 of brackets 41: which may be screwed to the window casing. The board may be secured directly inside of the window sash,

so that the outside of the board is exposed when the sashis partially raised or lowered,

as the case may be.

i The board or partition 1 provided with an-inlet opening 5 and with am outlet. opening 6. The outlet openim? 6 communicates to embrace the with an outlet piece 7 secured to the inner face of the board, which is preferably in the form of a short cylinder or pipe. The outlet opening may be opened or closed by a valve plate 8 supported in a guidcway formed in the flange of the outlet piece. The'inlet opening 5 communicates with the puter end of an inlet box .or casing 9 which 1s secured to the inner face of the board. The inner end of the inlet box is semi-cylindr cal in shape, and; is cut away to form a port 10-.

A centrifugal fan wheel 11 is mounted upon the board 1, and is provided with a snail casing 12 having a lateral inlet eye 13 and a tangential discharge 14. The fan wheel is secured to the shaft 14 of an electric motor 15 which is mounted upon the board 1. The rear side of the fan casing is secured to a cap 16 which forms the front end. of the motor casing. The cap 16 is provided with a. flange 17 fitting within a flange 18 on the motor casing, and held frictionally against. rotation by screws 19 which are provided with conical ends entering a V-shaped groove in the flange 17. This manner of supporting the fan casing enables the casing to he turned about the axis of the fan, and the parts are so arranged, that the discharge end 14 of the casing may be brought into engagement with the outlet piece 7, as shown'in dotted lines inFig. 2, or may be turned down into the full line position of Fig. 2. 'A cylinder 20 is secured to the eye 13 of the fan casing, and is arranged to fit within the send-cylindrical end of the inlet box 9. One side of this cylinder is cut away at '21 to form a port which is either open. to the inlet box or, open to the room within which the apparatus is located, according to the adjustment of the fan asing. The closed side 22 of the cylinder forms a valve which either closes the port 20 at the inner end of the inlet box, or cuts cated in Fig. 1, and in full lines in Fig. 2, and the valve plate 8 is placed in position to close the outlet opening 6 in the windowboard. With the parts thus adjusted, the port 20 in the inlet box is closed, and the eye of the fan is in communication .withthe inlet opening 5 through the inlet bogr an'd I port 21. The air wil-Lnov? bedrawn inthrough t'he inlet opening 5, and be jde-' tion indicated in Fig. 2, and the valve plate s will be removed.- Thedischarge 14- will now be in corhmiinication with the discharge opening 6. The adjustment of the ,casing into the dotted line positionturns the cylinder through-I a half revolution,

5 thus cutting ofi" communication between the eye of the 'fan and the inlet, opening 5, and openlng communication between the ,eye of the fan and the room within which. the ap-' paratus is located. When the 'fan is rotated, 20 air will now be drawn from the room through the eye of the fan casing andzwill be delivered from the discharge 1 t through the outletopening ti.

While it is preferred -toemploythe construction and arrangement of'parts shown' and described, and to provide for reversing the connections between the'eye and discharge of the fan casing so that air may be blown *in or exhausted out of the room by adjustment of the fan casing, it will be understood thatthis construction and arrangement is not. essential to the broader features of the invention, and that/the reversal of the flow of air through the parti- 3 5 tion-may be otherwise sec'ur'ed without departing therefrom. While the invention has been illustrated and described in connection with its application to a window Ventilating set, it will be understood that the invention 40 is not confined in its application to such use, but may be utilizedin other relations where it is desirable, to inducea current of air through a partition and to. reverse the direction of flow at will. 1 Having explained the nature and objectof the'invention, and specifically described one form of apparatus in which t. may be embodied, what I claim is 1. A ventilating apparatus, having, in combination, a partition ,providcd'with inlet and outletopenings, a fan, a fan casing provided with an inlet eye and aidischarge, and means for either opening communication between the inlet opening and eye and closing the outlet opening, or opening communication between the discharge and outlet opening and closing the inlet opening, substantially as described.
